You are a bad liar

Susan looked at Ivan, trying to hide her irritation. She decided that if he wasn't a prince, she would probably have called him an idiot to his face, but since he was a prince, she had to refrain from saying it out loud.

Her father looked at her for a moment without saying a word. He knew his kids, and he knew how sharp they both were, especially Susan, who could be very mischievous. What he was trying to figure out now was if Ivan's allegation had anything to do with the reason she was saying she wanted to remain in the palace and didn't want to get married yet. 

"Isn't Prince Harold's guard the one who showed us to our chamber?" He asked, and Ivan gave him a nod.

Now that it was being discussed, he remembered noticing how she had kept looking back while they were talking. Was the guard the reason for all of that? 

"Is it true that you are involved with him?" Her father asked calmly when she said nothing.
